Ask Ed: Grow Tip – Removing Powdery Mildew

Suffering from powdery mildew? That’s that white, powdery growth on top of the leaves—it almost looks like flour—it can kill your plants. Here is the simplest way of getting rid of it:

– Go to your local garden shop, or nursery, and buy a bottle of potassium bicarbonate

– Mix an ounce of potassium bicarbonate in a gallon of water and 1.5 cups (12 oz, 340 grams) of milk—I prefer non fat, because it is less oily—but whole milk works as well.

– Spray on your plants or dip them in it. It kills the living fungus and the potassium bicarbonate creates an alkaline environment that hinders germination of spores.
